My best shot

Reader Jim "Woody" Woods sent in his best photograph. He writes: "I went to the Civil War re-enactment of the Battle at Gettysburg held at El Dorado Park (at the end of May). I set my Olympus E-Volt 300 to multiple shot mode and waited till the cannon was about to be fired. I then just held down the shutter release hoping to get this photo and I obviously did. The only work I have done is crop it for content. The cannon fire has not been Photoshopped in. This is real cannon fire."
